It doesn´t work 🙁
For those still trying to fix it, I tried a lot of stuff and it’s still happening (since launch back in februari 9, I think?)
I tried all of the following ‘fixes’, nothing worked;
Tried every resolution / Full screen / Windowed etc.
Tried disabling V-sync / enabling it.
Tried +fps_max 60/75/144 in Advanced Launch Options (in Origin, Rightclick Apex > Game Properties)
Tried the Regedit fix
Tried uninstalling / re-installing it, on different Disks (C / D / E etc)
And many small ones more, can’t remember all of them. Nothing seems to work for me (Windows 7).
It has to be fixed on EA’s end. I read a lot about that there’s a problem in their coding. I highly doubt it can be fixed. I haven’t found any fix yet.
Tried all and it still doesnt work … please help
